Application filed September 7, 1912. Serial No. 719,084.

To all :whom it may concern:

Be 1t known that I, GEORGE B. THoRPE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois,"

have invented new and useful Improvements in Roller Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of my invention such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the references marked thereon,

which form part of this specification.

This invention relates to new, useful and novel improvements in roller screens for.

windows.

The object of the invention is to produce a simple, and eflicient device of this kind, comprising a spring actuated roller, upon which a screen is adapted to wind secured to the jambs of a window frame, and so adjusted that the entire opening of the window is covered by the screen, thereby permitting the adjusting of both the upper and the lower sash of window as desired.

My invention consists, further, in various other details of construction, combinations, and arrangements of the parts, which will be hereinafter fully described, and then specifically defined in the appended claims.

I hereby illustrate my invention in the accompanying drawings, in which Figure 1 is a left hand, side, sectional view of a window frame, showing attachment of the cap the screen and the roller thereto. Fig. 2 is a top view of a spring roller looking downward. Fig. 3 is a detail view of a combined spring and bolt. Fig. 4 is a de tail front elevation and perspective view of a bracket which holds the stationary pintle. Fig. 5 is a combined view of a roller Fig. 2 and the bracket Fig. 4 showing them attached, with part cut away on the line B and B of the roller, Fig. 2 and on the line A and A of the bracket. Fig. 6 is a perspective top view of the bracket which holds the revolving pintle of the roller Fig. 2. Fig. 7 is a face view of a pintle as attached to the end of a roller (Fig. 2) showing the bolt and opening through the pintle with the pawl dislodged from the opening in the top of the pintle by a bolt. Fig. 8 is a top per spective view of a cap showing the hangers by which it is attached to a wmdow frame.

The object of my improvement is to secure-a cheap, practical window screen, which the above description and illustrations show; therefore I have adopted a screen, which works on the principle of the spring-roller window shade; now in universal use.

Myimproved roller is adjustable, in so much that it can be converted from a pawl controlled spring actuated eccentric roller, into a free spring actuated roller, this is accomplished bythe spring actuated roller having pintles on the ends, one of said pintles having an opening therethrough in which the pawls engage to prevent the roller revolving; and through which a bolt ascends dislodging the pawls thereby permitting the roller to revolve freely.

For manufacturing, I prefer the combined bolt 6 and spring 6 shown in Fig. 3. The pintle 11 when placed in the opening 10 rests on the seat 3, of the bracket Fig. 4. with the edge coming into contact with the spring 6 of the bolt 6 at a suflicient distance from the end of the pintle where the spring 6 is secured by a rivet at 7, causing the bolt 6 to ascend and fill the opening 2 in the pintle, thereby disengaging or forcing the pawls therefrom. The pawls 5 come into use when adjusting the pintle in the bracket, or when removing the roller 1 from the bracket, as is sometimes necessary when the tension is not strong enough, or other repairs required, and this is done automatically by raising the roller 1 from the bracket Fig. 1, the spring bolt 6 having the spring 6, which is secured by a rivet at 7 to the under side of the pintle 11, springs down, leaving the hole 2 in the top of the pint-1e 11 open which the pawls enterthereby preventing the roller .1 from revolving.

To strengthen the tension 'of the spring in the roller, when required, pull the screen down a foot or tworemove the roller 1 from the bracketsroll up the screen on the roller and replace the roller in the brackets. The pawls 5 are very essential to the working of the device. Without them it would be almost impossible to control the recoil of the spring inside of the roller 1 when removed from the brackets.

The brackets should be made of Inetahand theopenings 10 and 14, shown in F1g.4 and Fig. 6, out out to receive and hold the pntles 11 and 12, and the edge of the metal bent back so as to form a ledge of sufiicient depth to keep the'face of thebracket at a; proper distance from the jamb or lining of the window frame, to which the bracket is attached by the screws 4: so as to prevent the end of the pintle coming into contact with the amb or lining of the frame. The brackets should be made by the metal stamping process out of one piece of metal. The cap Fig. 8 can be made of wood or metal and should be fitted close to top of the window, so as to prevent the entrance of insects into the apartment, and is suspended by the hangers 16, fastened by screws so as to hangv down on an angle with the lower edge resting on oragainst the screencloth 17 which "is rolled upon the roller 1 which it will follow downward by gravity and is raised by the increasing pressure of the bulk of the roller as the screen is wound upon the roller by'the raising of the screen in the window. The screen c1oth17 should be secured by wire bands surrounding the roller which are secured'to the roller by'tacks or otherwise. witli thestationary pintle 11 to the left hand side, therevolving pintle 12 to the right. Of course, this arrangement could be re versed where there is sufiicient space on the jambs of a window to permit the screen working freely inside the sash of a window, orthe-screen could be attached to the outside of the frame of a window with'the sash inside if desired, by protecting it with a.

sheltercap. At the bottom is a cross bar 18 which should'be' the same length as the opening between the guide tubes on bothsides of the window. "The weight of the cross bar '18 should be adjusted to counteract the ten- 'sion-ofthe spring in the roller 1 thereby holding the screen taut and where it is desired for itto stay, as it is raised or low- The screen clot-h 17 is f 'secur'ed'at the bottom between the bar 18 'a'nd the strip 15 by rivets, and the strip 15 ered in the window.

should b'ethe same length as the width of t -he screen cloth 17. The ends of the strip 15 should be flanged to engage/with the guide in which it slides.

J "'This device should be attached to a win dow 'asifollows: By securing the bracket Fig. 4 with screws & to the left hand side of the "window, and the bracket 14 to the right hafid side with a screen guide on each side'jofthewindow, and the follower cap 13 securedtothe top of the'window frame or j'amb lin'i'ng by the hangers16 with screws, the screen cloth being wound upon the roller with tension properly adjusted. Place the revolving pintle "12 in the hole 14 of the brackets and adjust the other pintle 11 in thebpenirrg l0 with'the spring 6 which is secured to the'bottom of pintle 11, resting on the seat 3 of the opening 10 in bracket Fig. 1. *'-Tl1en place the screen, which is secured' to-the metal strip 15, into the slot in -the top of the screen guides on each side of the'windowg-pull down the screen to the sill of the window, see 'that'it works easily tap-and own in the window; "The friction 5- 1 v '7- =:-W;..

of cross strip and screen in the guides and the weight of the cross bar 18, if properly adjusted, will offset the strength of the spring in the roller 1 and cause the screen to stay where placed. For convenience in handling, when raising or lowering the screen, handles 25 should be secured to the bar 18 about 4 inches from either end.

lVhat I claim and desire to secure by Letters Patent is:
